Gary, what is really important in a torqued fastener is the tension produced
in the fastener by the torquing process.  Normally nut torque is specified
for "dry" threads.    If a fastener is lubricated and then torqued to a
"dry" specification, it can be overtorqued even to the point of failure
because there is less friction between the lubricated threads to resist the
torquing process.  That is, the tension produced in the fastener will be
higher at the point where the specified torque is reached on the torque

If a torque is specified for lubricated threads, it will be stated as such.

On another site I frequent, regarding modern Mercedes, someone last week 
recommended that folks should use anti-seize on lug bolts. Seems to me I
that this is not a good idea on any bolt that needs to be tightened to a 
specific torque spec. Can someone who is more knowledgable enlighten me on
